张家港大桥主桥为40+70+40（m)的预应力混凝土连续箱梁结构，采用三向预应力体系，张拉0号块竖向预应力筋时，发生断裂，本文通过力学模式假定，分析断裂机理，并提出了施工控制对策
The main bridge of Zhangjiagang Bridge is a 40+70+40 (m) prestressed concrete continuous box girder structure with a three-way prestressing system, and when the vertical prestressing tendons of block 0 are tensioned, fracture occurs, and this paper analyzes the fracture mechanism through the assumption of the mechanical model, and proposes the construction control countermeasures
